I am no expert on late season bowhunting, but I have done quite a bit of it here in Southwestern pa. One thing I have noticed is that in my area the deer do concentrate on the food sources. Usually we are well into the bitter cold weather and most of the deer movement was mid afternoon. I guess because it is usually the warmer part of the day. they must be trying to conserve energy (body heat) since the food is scarce. More input less output. Hope you find that buck!
